1996 Cav PCM location, tach hookup

[jbray]

Can anyone tell me the location of the PCM for 1996 2.2L Cavalier. Also which wires out of the PCM are going to the coil packs that I would use for tach input. I have info that it is c3-32 white wire and c3-31 orange wire. Is this correct? When I hook up a tach, am I going to need a tach adapter, or is there a way around using one.

Thanks

I am actually doing the exact same thing on my car with the tach. I have a Sunpro, which requires an adapter that you have to order from them. I think its 15 bucks.

can you tell me if you are hooking the tach adapter up at the coil packs or at the PCM and can you tell me the location of the PCM on this car.

You actually have to hook the adapter up to the orange and white wires. And they are at the back of the motor, underneath the iginition controle module, and the four ignition coils. You have to crawl under the car to get to them.
